"This is just another example of the Gillard Government trying to intimidate small business to not pass on or talk about the impact of the carbon tax."

The Australian Competition and Consumer Commission has set up a hotline for members of the public to make complaints about misleading carbon tax claims.

The tactic is a further sign that both sides of politics are preparing to ramp up their campaigning efforts surrounding the tax.

On Tuesday Mr Abbott told a meeting of Coalition MPs that he and other senior party figures would be campaigning "across the country", warning people the tax would push up the cost of living and threaten jobs.

Labor is also preparing a coordinated campaign this weekend to reassure the community about the effects of the tax.

Special Minister of State Gary Gray plans to visit the South Australian city of Whyalla on Sunday - a community Mr Abbott said would be "wiped off the map" because of the carbon pricing scheme.

Mr Abbott visited an RSPCA compound in Canberra on Tuesday to point out that "thousands" of charities would be worse off under the tax despite Government reassurances.

The head of the RSPCA in the ACT, Michael Linke, estimates the cost of the carbon tax will be somewhere between $5,000 and $10,000 per year for the local organisation.
